Oxidation of α-hydroxy acids by an oxidation-active flavin mimic bearing a bipyridin-6-ylmethyl moiety in the presence of Zn2+ and a base in tert-butyl alcohol
Abstract
A benzo-dipteridine (BDP) having a bipyridin-6-ylmethyl moiety oxidizes α-hydroxy acids to give α-keto acids in the presence of Zn2+ and Et3N in ButOH, whereas a BDP bearing a bipyridin-5-ylmethyl moiety is unable to oxidize them under the same conditions; this is the first example of a D-lactate dehydrogenase model.
